tom, and with triangular end walls. Lying `fiat against 9' one-half of each end wall is an upright, inwardly extending, triangular reverse fold, the opposite sides of which are secured face-to-face. The reverse fold is integrally joined to the adjoining end wall along the center of 'that wall. Extensions of more or less triangular shape project lengthwise of the body away from the upper edges of each end wall and reverse fold. Side and end aps extend downward from the upper edges of the side walls and the outer edges of the end wall extensions. The side aps not only reinforce the body, but they also hold it upright.

The 'body is reinforced by side aps 8 that extend down from the upper edges of its side walls. These flaps are at least as deep as the body, so that they form legs to holdV the body upright. There also are end aps 9 extending downward from the outer edges of end wall extensions 6.` These flaps are continuations of the side aps and holdl the extensions down. l The side and end flaps may be cut to givethe dish dif-` ferent appearances. They also may be decorated by printing to represent various objects. For example, when this dish is used for ice cream, it is desirable to have it, represent a ship, so that a young consumer who has empf tied the dishcan brag that he sank a ship. In such a case, the side and` end flaps can have port holes and anchors printed on them, and the end extensions will repre- V sent decks, from which removable flags or pennants 11 can be ilown by inserting them in slits 12. If a battleshipis desired, pictures of guns can be printed on'the flaps.

The `dish that has just been described is formed from a single sheet of cardboard by folding it into the shape shown. The sheet has the general shape of the one shown bottom side up in Fig. when a dish is to represent a ship. The sheethas fold lines pressed into it, indicated by the broken lines,` along which it can be folded p easily. It will be seen that at opposite ends there are The preferred embodiment of the invention is illustrated in the accompanying drawings, in which Fig. 1 is a side view of my dish;

Fig. 14 is an end view of Fig. 13; and

Fig. 15 is a fragmentary plan view of the blank as shown in Fig. 13, but with the triangular projection folded back against the end wall.

Referring to Figs. 1 to 4, it will be seen that the dish has a trough-like body 1 or receptacle portion provided with inclined side walls 2 that meet at the bottom along the center of the dish. The end walls 3 of the body therefore are triangular. Inside the dish, half of each end wall is overlaid by a vertical triangular reverse fold 4, the opposite sides of which are joined faceto-face and are integral with the end wall along its center directly above the point where the side walls come together. Integral with the upper edges of the end walls and the upright reverse folds are extensions 6 and 7, respectively, of generally triangular shape which project more or less horizontally lengthwise of the dish away from its body.

triangular areas 4a, 4b, 7a and 7b that have been coated on the bottom with an adhesive. To make the blank from which the dish is formed, the sheet is folded along its longitudinal center line Vand transversely across the ends of side walls 2 and side flaps 8 to provide a reverse fold at each end located between the at rectangular sides of the blank, as indicated in Figs. 6 and 7. In doing this, triangular portions 4a and 7u are poined, by the adhesive to triangular portions 4b and 7b to form reverse folds 4 and extensions 7. This is all done by the manufacturer, and it is this flat blank of Fig. 6 that is shipped to the retail store.

When it is desired to convert the flat blank of Fig. 6 into a dish or other receptacle, the opposite sides of the blank are spread apart, which has the effect of pulling the end walls and end flaps and extensions 6 out from between the side walls and into the position shown in Figs. 8 and 9, but the adhesively joined reverse folds continue to project toward each other. The blank is not left in this position, but the end walls and reverse folds are pulled farther away from each other and then the opposite sides of the blank are pressed back against each other as shown in Fig. 10. The blank then has the appearance from the side shown in Fig. 11. In other words, the end portions of the blank which projected between its oppo site sides in Fig. 6, now project away from the ends of those sides.

The next step is to fold down the side and end aps 8 and 9 as shown in Fig. 12. Following this, the blank again is opened to pull the end walls 3, extensions 6 and end aps 9 up into the upright position shown in Figs. 13 and 14. The adhesively joined reverse folds at the opposite ends will then project toward each other again. The next step is to fold the reverse folds 4 over against half of each end wall 3, as shown in Fig. l5, which simultaneously folds each extension 7 against half of an end wall extension 6. At this point, end aps 9 lie substantially liat against end walls 3, and side flaps 8 lie substantially fiat against side walls 2.

The final step in setting up the dish is to bend extensions 6 and 7 outwardly and down to substantially horizontal positions, where they will be held by end aps 9 A and represent decks at the bow and stern of a ship. The dish or ship is now in the shape shown in Figs. 1 to 4 and is ready for use. It will be seen that when the end extensions arc folded down in this manner, the side and end apsjswing rout away fromthe body of the dish into substantially upright position. vThe side flaps stiien the'body and serve as legs to hold it upright.

This kdish-isintended :to .be thrown awayafter it is used.and.it` is inexpensive enoughfforthat purpose. The rectangular blanks of Fig. .6 areeasy, to ship and to han dle'lbecause they are Bat, andV4 caneas'ily'be packed or bundled., -It requires` only a .few .seconds to form `the blank gintoa dish. No fastening Imembers are required and no locking togetherof tongues andslots isnecessary. The only adhesive that lis 4usedis applied by the manufacturerto theoriginal tlatsheet.l
